How does garlic work against fungus gnats?
You probably first thought of the strong smell of the garlic bulb when you heard that the cloves can be used against the fungus gnat. However, the aroma hardly plays a significant role in combating it. Rather, it is the allicin contained in it that not only drives away the pests, but also kills them. Allicin is a sulfur-containing acid that is found in high concentrations in garlic. It has a toxic effect on the fungus gnat.

There are two options for releasing the contained allicin:
Variant 1
- Cut the tip of a garlic clove with a sharp knife.
- Insert the entire tuber into the substrate of the affected plant.
Variant 2
- Peel a garlic bulb.
- Detach the individual toes from each other.
- Then roll the dice.
- Distribute the garlic cubes over the potting soil.

If the application does not bring any visible success, you should combine the garlic method with other home remedies against the fungus gnat. It is important that you always choose organic methods. Chemicals not only harm the fungus gnats, but also your plants.
